This study is aimed to investigate the effect of luteinizing hormone (LH) on maturation and fertilization in vitro of ovine oocytes.The ovine oocytes were cultured in vitro in medium with or without LH,and then checked by confocal laser scanning microscope to observe the distribution of cortical granules stained with FITC-LCA during different maturation periods.Similarly,some in vitro matured oocytes were also fertilized in vitro for analysis of their developmental potentiality further.After being cultured in vitro for 4 h,there were significant differences about the rate of germinal vesicle break down (GVBD) between the treatment (with LH) and the control groups (without any hormones) (36.76% vs 18%,P
